    摘要: A system for detecting an interface between polymer-rich phase and solvent-rich phase comprising a liquid-liquid separator configured to receive a polymer solution as an inlet stream produced in a solvent-based polymerization reactor through an inlet feed, wherein the tank is configured to permit the stream to separate into a polymer rich phase and a solvent rich phase; a first sonic transponder for sending a first sonic signal from either a top or bottom of the liquid-liquid separator and for receiving a first reflected portion of the sonic signal, the reflected portion of the sonic signal created by the passage of the sonic signal through a liquid-liquid interface between the solvent rich phase and the polymer rich phase is provided.
